    Answer:

    x=1

    Step-by-step explanation:

    If f(x)=6x-2 and g(x)=-3x+7, then the equation

    f(x)=g(x)

    is equivalent to the equation

    6x-2=-3x+7

    Add 3x to both sides of the equation:

    6x-2+3x=-3x+7+3x\\ \\(6x+3x)-2=(-3x+3x)+7\\ \\9x-2=7

    Add 2 to both sides of the equation:

    9x-2+2=7+2\\ \\9x=9

    Divide by 9:

    x=1
